Installation notes

Installation requirements
The tumble dryer must only be installed and commissioned by Miele Customer Service Department or an authorized dealer.

The tumble dryer must be installed in accordance with all relevant regulations and standards.
The dryer must only be operated in a room that has sufficient ventilation and which is frost-free.

Electrical connection
The electrical connection must be established by a qualified electrician.
The electrical connection may only be made to an electrical system provided in accordance with all appropriate local and national legislation, regulations, and guidelines.  Please also observe the regulations set out by your insurance provider and energy supplier, accident prevention regulations, as well as recognized codes of practice.
Reliable and safe operation of this tumble dryer is only ensured if it has been connected to the mains electricity supply.

The required supply voltage, power rating, and fuse rating can be found on the data plate on the tumble dryer. Ensure that the supply voltage matches the voltage quoted on the
data plate before establishing the electrical connection to the tumble dryer.
Connection to a supply voltage other than the one quoted on the data plate can damage the tumble dryer if the voltage is too high.

If more than one voltage is specified on the data plate, the tumble dryer can be converted for connection to the relevant input voltage. This conversion must be performed by the Miele Customer Service Department or by an authorized dealer. During the conversion, the wiring instructions given on the wiring diagram must be followed.
The tumble dryer can either be hard-wired or connected using a plug-and-socket connection in accordance with IEC 60309-1. For a hard-wired connection, an all-pole isolation device must be available at the installation site.

An isolation device is a switch that ensures a contact opening of more than 3 mm. These include circuit breakers, fuses, and contactors (IEC/EN 60947).

If the mains supply cannot be permanently disconnected, the isolation device (including plug and socket) must be safeguarded against being switched on either unintentionally or without authorization.

Tip: We recommend connecting the tumble dryer to the power supply via a plug and socket so that it is easier to conduct electrical safety checks (e.g. during maintenance or
repair work).
The tumble dryer must not be connected to devices such as timers which would switch it off automatically.

If local regulations require that a residual current device (RCD) is installed, a type B residual current device (sensitive to universal current) must be used.

Gas connection
The gas connection must only be carried out by a registered installation technician in accordance with the applicable national regulations (see installation instructions).
The use of a gas socket is not permitted at the specified heater rating as the flow rate is too low. The gas heating is configured at the factory in line with the gas specifications on the sticker on the rear of the appliance.
If the gas family is changed, a conversion kit must be requested from the Miele Customer Service Department (please specify the appliance type, serial number, gas family, gas group, gas connection pressure, and country of installation). Follow the installation instructions. This conversion may only be carried out by a registered specialist.

Air intake/exhaust air
The tumble dryer may only be operated when the ducting has been connected properly
and the room is sufficiently ventilated.
Accessory parts may only be fitted when expressly approved by Miele. If other parts are used, warranty, performance, and product liability claims will be invalidated.

Cable gland M20

Gas connection

Nominal heat rating 36 kW
Machine-side connection according to ISO 7-1
To connect the gas appliance, a corrugated metal hose line made of stainless steel according to DIN 3384
must be used. The shut-off device must be provided on-site. Due to an insufficient flow rate, the use of a
gas socket is not permissible with the specified heating output.		 ½”
Connection thread for natural gas, on-site (internal thread) ½”

Waste air/gas

Max. nominal airflow invented mode (PDR 9xx only) 1010 m³/h
Max. nominal airflow (PDR 5xx only) 1010 m³/h
Max. permissible pressure loss 240 Pa
Connection on machine side (ext. diameter) 150 mm
Connection pipe provided on-site (int. diameter) 150 mm
Max. temperature 80 °C
This tumble dryer is a gas-burning machine without a flow-operated safety device with a fan downstream of the heat exchanger (technical design: B22). Waste gas pipework must be pressure-tight.  Waste gas connections should be performed in accordance with national and local regulations and may require approval.
As relative humidity inside the vent ducting can be as high as 100%, suitable measures must be taken to prevent a backflow of condensate into the machine.

Air intake

Standard connection: air intake from the installation site
Recommended free air intake cross-section into the room:
(equivalent to 3 times the exhaust air cross-section of a machine).
There must be sufficient air intake to the installation site to match the air outlet volume.		 531 cm²
Alternative connection: air intake connection directly from outdoors
Connection sleeve on machine side (internal diameter)
Connection pipe provided on-site (external diameter)		 161 mm
160 mm
Removing the protective cover exposes live parts. For safety reasons, a pipe must be installed from the tumble dryer’s central fresh air intake (over a minimum length of 900 mm) and secured with 2 screws.
